Then, the CPU 62 reads a program stored in the ROM 64 into the memory and executes the program, thereby achieving implementation of respective functions of the respective units in the terminal device 100 or the management device 200.

Note that, in each of the drawings, a configuration of a portion irrelevant to the essence of the present disclosure is omitted and not illustrated.

Furthermore, the terminal device 100 or the management device 200 in FIG. 1 is implemented by arbitrary combination of arbitrary hardware of the computer 60 (FIG. 3) and software, and the computer 60 includes the CPU 62, memory (RAM 66), a program loaded onto the memory, the memory unit (ROM 64) like a hard disk to store the program, and the interface (I/O 68) for network connection in FIG. 3. Additionally, note that those skilled in the art understand that the implementation method and the device include various modified examples. Each of functional block diagrams including other embodiments described below illustrates not a configuration per hardware but a block per logical function.

In the terminal device 100 or the management device 200 according to the embodiment of the present disclosure, the CPU 62 executes various kinds of processing operation corresponding to a computer program 70, thereby implementing the above-described respective units serving as various functions.

A first computer program according to the embodiment of the present disclosure is described such that the computer 60 provided to implement the terminal device 100 is caused to execute procedures to: read a stealth mark which is invisible under visible light and visible under light of a predetermined wavelength and includes an impregnated region formed a fluorescent coloring material and formed on a spectacle lens; and read and input identification information from the stealth mark that is invisible under the visible light and visible under the predetermined wavelength.

Furthermore, a second computer program according to the embodiment of the present disclosure is described such that the computer 60 provided to implement the management device 200 is caused to execute procedures to: store management information I on a spectacle lens; receive the identification information from the stealth mark input unit of the terminal device 100; and select management information i corresponding to the stealth mark from the storage unit 201.

A management method by the spectacle lens management system 1 of the present embodiment in the above-described configuration will be described below.

FIG. 4 is a flowchart illustrating exemplary operation of the spectacle lens management system 1 according to the embodiment of the present disclosure.

In a spectacle lens management method according to the present embodiment, the stealth mark reading unit 102 of the terminal device 100 reads a stealth mark 501 that is invisible under visible light and visible under light of a predetermined wavelength and includes an impregnated region formed from a fluorescent coloring material and formed on a spectacle lens (step S101), the stealth mark input unit 101 reads and inputs identification information from the stealth mark 501 that is invisible under the visible light and visible under the predetermined wavelength (step S102), the terminal device 100 transmits the identification information (step S103), the data processing unit 202 of the management device 200 receives the identification information from the stealth mark input unit 101 (step S111), and the data processing unit 202 selects, from the storage unit 201, management information i corresponding to the stealth mark 501 (step S112).

As described above, the spectacle lens management system 1 according to the present embodiment can manage information on a spectacle lens by reading a stealth mark formed on the spectacle lens. Since the stealth mark includes an impregnated region formed from a fluorescent coloring material, the stealth mark cannot be visually recognized under the visible light and can be confirmed only when irradiated with the predetermined wavelength. Therefore, there is no problem in usual use as a spectacle lens, and history information on a spectacle from production to distribution of the spectacle lens can be managed by a stealth mark. As a result, a spectacle store can utilize the spectacle lens management system of the present disclosure for customer management, customer support, and after-sales service, more specifically, can utilize the system as: a chart-less system by managing customer clinical records with electronic data; a sales promotion tool to manage spectacle lens manufacturer's product warranty, store's product warranty, issuance timing of a direct mail; assistance for reproduction of a spectacle lens, and the like.

Second Embodiment

FIG. 5 is a functional block diagram illustrating a configuration of a spectacle lens management system 1 according to a second embodiment.

In the present embodiment, different from an embodiment described above, provided are: a terminal device 100a installed in a factory of a spectacle lens manufacturer; a terminal device 100b installed at a sales office of the spectacle lens manufacturer; and a terminal device 100c installed at a spectacle store (hereinafter, the terminal devices 100a to 100c are collectively referred to as “terminal device 100”). Thus, the terminal devices are installed in the factory of the spectacle lens manufacturer, the sales office of the spectacle lens manufacturer, and the spectacle stores, and information on manufacture and information on sales are aggregated, and therefore, an inquiry regarding an individual product from an end user can be quickly handled. The terminal device 100a includes a display unit 103 that displays management information i transmitted from the management device 200. Meanwhile, the terminal device 100b also includes a display unit in a manner similar to the terminal device 100a, although not illustrated.

FIG. 7 is a functional block diagram illustrating a configuration of the terminal device 100c.

Different from the embodiment of a terminal device 100, the terminal device 100c further includes a sales customer information input unit 104 to input sales customer information. Examples of the sales customer information include a name, a date of birth, optometry information, prescription information of a spectacle lens, a date of sales, and the like related to a customer. The sales customer information may be input by, for example, an input device such as a keyboard or a mouse.

Different from the embodiment of the terminal device 100, the terminal device 100c further includes a reproduction order information input unit 105 to input reproduction order information in a manner correlated to identification information of a spectacle lens.

The term “reproduction order” means producing a spectacle lens same as a spectacle lens previously produced.

The term “reproduction order information” includes identification information of a spectacle lens, number of ordered products, and the like.

Referring again to FIG. 5, the management device 200 includes, as management information I in the storage unit, production information 203a, sales information 203b, and customer clinical record information 203c.

The terminal device and the management device in the present embodiment at least have functions similar to those of the terminal device 100 and a management device 200 of the above-described embodiment. A data processing unit 202 of the management device 200 is adapted to store the sales customer information in a storage unit 201 in a manner correlated to identification information of a spectacle lens.

Examples of the sales customer information include personal information such as a name and a date of birth, optometry information, prescription of a spectacle lens, a date of sales, and the like related to a customer.

The data processing unit 202 of the management device 200 further includes a reproduction information processing unit 204 that selects, from the storage unit 201, management information i including prescription information on the basis of identification information of a spectacle lens, and transmits the selected information to another terminal device (for example, terminal device 100a or 100b).

The data processing unit 202 of the management device 200 further includes an expiration date management unit 205 that transmits expiration date information to a terminal device 100a that maintains a spectacle lens that has passed a predetermined period from a production date of a spectacle lens stored in the storage unit 201.

Different from the above embodiment, the management device 200 has an access management unit 207 that restricts information access from each terminal device 100. Since there is a problem in information security because the information is shared among respective business entities such as a spectacle lens manufacturer and a spectacle store, the access management unit 207 is provided.

For example, a security policy is set in the management device 200 for each terminal device 100 by an administrator as security measures for information accumulated in the management device.

A security policy for each terminal device 100 is managed by the access management unit 207 of the management device 200. Each terminal device 100 in the spectacle lens management system 1 is set, by the access management unit 207 of the management device 200, to have one of policies out of a plurality of levels of policies.

FIG. 6 is a table illustrating access permission levels in respective policies in the spectacle lens management system 1 according to the embodiment of the present disclosure. In the present embodiment, the management device 200 sets, as a base policy for the terminal device 100, a policy 1 indicating access prohibition to the storage unit 201. Furthermore, the access management unit 207 may change, in accordance with a user of the terminal device 100, the policy to one of the policies 2 to 3 which permit access to the storage unit 201.

In the present embodiment, the terminal device 100 and the management device 200 are connected to each other via a network 3.

The management device and the terminal device of the present embodiment are also implemented by arbitrary combination of hardware of a computer 60 and software in FIG. 3 described in the above embodiment. The respective functions of the respective units in the management device and the terminal device can be implemented by a CPU 62 of the computer 60 reading, into a memory (RAM 66), a program stored in a memory unit (ROM 64) such as a hard disk, and executing the program.

In the present embodiment, the terminal device 100a installed in a factory transmits the management information i to the management device 200 in a manner correlated to identification information on a stealth mark, and the data processing unit 202 of the management device 200 stores, as spectacle lens production information 203a, the management information in the storage unit 201.

Here, examples of the management information i include a lens material, a design type, a producing factory, a production date, prescription information, spectacle lens order information, production history information, customer management information, quality information, surface treatment information, layout information, order information, R/L identification information, design reference point information, and the like.

The terminal device 100a reads the identification information from a stealth mark attached to a spectacle lens and transmits the same to the data processing unit 202 of the management device 200, and the data processing unit 202 selects, from the storage unit 201, management information i corresponding to the stealth mark and returns the selected management information i to the terminal device 100a.

The terminal device 100a displays, on the display unit 103, the management information i transmitted from the management device 200. Since information corresponding to an individual spectacle lens can be displayed by displaying the surface treatment information, layout information, and the like in a producing process as the management information i, a paper instruction attached to a spectacle lens in the factory can be eliminated.

FIG. 8 is a flowchart illustrating exemplary operation of the spectacle lens management system 1 according to the embodiment of the present disclosure.

In the present embodiment, the spectacle management system 1 inputs a request for use from each terminal device 100 (step S250), and the management device 200 receives the request for use from each terminal device 100 in the access management unit 207, for example, when content of a request is input on a request screen (step S260). In a case where content of a request is “display” (step 261), the access management unit 207 first confirms authenticity of access, and then generates authorization information when the authenticity is OK (step S262), and then transmits the generated authorization information to the terminal device 100 (step S263), and the terminal device 100 displays the authorization information on the display device 103 (step 252). In a case where content of a request is “rewrite” (step S265), the access management unit 207 first confirms authenticity of access, and then rewrites information in the storage unit 201 with information input from the terminal device 100 (step S267) when the authenticity is OK (step S266).

Additionally, a policy to indicate access limitation to the storage unit 201 of the management device 200 is set to one of the policy indicating access prohibition and the policies 2 to 3 which permit access to the storage unit 201 described above.

The spectacle lens management system 1 of the present embodiment can manage an expiration date of a spectacle lens in a factory.

FIG. 9 is a flowchart illustrating exemplary operation of the spectacle lens management system 1 according to the embodiment of the present disclosure.

In the spectacle lens management method according to the present embodiment, the expiration date management unit 205 of the management device 200 selects a production date of a spectacle lens stored in the storage unit 201 (step S201), and the expiration date management unit 205 determines whether a predetermined time limit has passed (step S202), and in a case where the predetermined time limit has passed, the management device 200 transmits the expiration date information (step S203), the terminal device 100a receives the expiration date information (step S211), and the display unit 103 displays the expiration date information (step S212).

With the above-described management method, it is possible to manage inventory of spectacle lenses, and information such as an old spectacle lens substrate having passed the predetermined time limit can be displayed.

In the present embodiment, the terminal device 100b installed in a sales office transmits, as the management information i, distribution route information, a sales contact, a delivery date, and the like to the management device 200 in a manner correlated to identification information on a stealth mark, and the data processing unit 202 of the management device 200 stores the same in the storage unit 201 as sales information 203b.

The terminal device 100b reads identification information from a stealth mark attached to a spectacle lens and transmits the same to the data processing unit 202 of the management device 200, and the data processing unit 202 selects, from the storage unit 201, management information i corresponding to the stealth mark and returns the selected management information i to the terminal device 100b. The terminal device 100b displays, on the display unit 103, the management information i transmitted from the management device 200. With the spectacle lens management system of the present embodiment, for example, an inquiry from a store or an end user can be handled by acquiring management information on an individual spectacle lens.

In the present embodiment, the terminal device 100c installed at a store transmits the sales customer information as the management information i to the management device 200, and the data processing unit 202 of the management device 200 stores the same as the customer clinical record information 203c in the storage unit 201 in a manner correlated to the identification information on the stealth mark.

FIG. 10 is a flowchart illustrating exemplary operation of the spectacle lens management system 1 according to the embodiment of the present disclosure.

In the spectacle lens management method according to the present embodiment, the sales customer information input unit 104 of the terminal device 100c inputs sales customer information (step S221), the terminal device 100c transmits the sales customer information to the management device 200 (step S222),

the management device 200 receives the sales customer information (step S231), the data processing unit 202 stores the sales customer information in the storage unit 201 (step S232), the management device 200 transmits the sales customer information to the terminal device 100a (step S233),

the terminal device 100a receives the sales customer information (step S241), the stealth mark reading unit 102 reads a stealth mark formed on a produced spectacle lens (step S242), the stealth mark input unit 101 reads and inputs identification information from the stealth mark (step S243), the terminal device 100a transmits the identification information to the management device 200 (step S244),

the management device 200 receives the identification information (step S234), and the data processing unit 202 stores the sales customer information in the storage unit 201 in a manner correlated to the identification information of the spectacle lens (step S235).

With the above-described management method, a customer clinical record can be automatically created.

A store generally creates a clinical record for each customer in accordance with prescription information at the time of producing a spectacle, but a large storage space is required in the store. A paper clinical record created by the store may be substituted by managing the customer clinical record information with the management system of the present embodiment.

The terminal device 100c installed at a store in the present embodiment transmits, to the management device 200, reproduction order information corresponding to identification information of a spectacle lens in accordance with a reproduction order from an end user, the reproduction information processing unit 204 of the management device 200 selects, from the storage unit 201, the management information i including prescription information on the basis of the identification information of the spectacle lens, and then transmits the same to another terminal device (e.g., terminal device 100a or 100b).

FIG. 11 is a flowchart illustrating exemplary operation of the spectacle lens management system 1 according to the embodiment of the present disclosure.

In the spectacle lens management method according to the present embodiment, the stealth mark reading unit 102 of the terminal device 100c reads a stealth mark (step S251), the stealth mark input unit reads and inputs identification information from the stealth mark (step S252), the reproduction order information input unit 105 inputs reproduction order information in a manner correlated to the identification information of the spectacle lens (step S253), the terminal device 100c transmits the reproduction order information to the management device 200 (step S254),

the management device 200 receives the reproduction order information (step S261), the data processing unit 202 selects, from the storage unit 201, management information i corresponding to the identification information of the spectacle lens (step S262), and the management device 200 transmits the reproduction order information and the management information i to the terminal device 100a (step S263),

the terminal device 100a receives the reproduction order information and the management information i (step S271), and the display unit 103 displays the reproduction order information and the management information i (step S272).

In a case where there is a spectacle reproduction order from an end user, a store staff can easily place an order for reproduction without obtaining necessary information for reproduction, such as a prescription of the spectacle lens, by reading identification information from a stealth mark attached to a spectacle lens and transmitting the same to the management device 200 by using the spectacle lens management system of the present embodiment.

[Spectacle Lens]

A spectacle lens of the present disclosure will be described in detail below.

A spectacle lens may include a substrate, a primer layer, a hard coating film, and an anti-reflection film. It may be that a stealth mark be impregnated with any one selected from a group consisting of a substrate, a primer layer, and a hard coating film.

FIG. 15 is a schematic diagram illustrating a structure of a spectacle lens of the first embodiment. A spectacle lens 500 has a stealth mark 501 formed near a boxing center of the spectacle lens. The stealth mark 501 is a two-dimensional code 501a including an impregnated region with a fluorescent coloring material. As a stealth mark, a design reference point 501c and a frame pattern 501d are included.

The stealth mark 501 may not be necessarily formed near the boxing center but inside the frame pattern.

In the spectacle lens of the present embodiment, the spectacle lens becomes visible when irradiated with light having a predetermined wavelength, for example. Therefore, when the spectacle lens is used as an ordinary spectacle, the stealth mark is not visually recognized but becomes visible when irradiated with the light having the predetermined wavelength, and the two-dimensional code becomes readable.

The fluorescent coloring material may be a fluorescent pigment or a fluorescent colorant.

From the viewpoint of providing a stealth mark, examples of the fluorescent pigment include C.I. Pigment Yellow 12, 13, 14, 17, 20, 24, 55, 74, 83, 86, 93, 97, 98, 109, 110, 117, 120, 125, 128, 137, 138, 139, 147, 148, 150, 151, 153, 154, 155, 166, 168, 180, 185, C.I. Pigment Orange 16, 36, 43, 51, 55, 59, 61, 71, C.I. Pigment Red 9, 48, 49, 52, 53, 57, 97, 122, 123, 149, 168, 175, 176, 177, 180, 192, 202, 209, 215, 216, 217, 220, 223, 224, 226, 227, 228, 238, 240, 254, 255, 272, C.I. Pigment Violet 19, 23, 29, 30, 37, 40, 50, C.I. Pigment Blue 15, 15: 1, 15: 3, 15: 4, 15: 6, 22, 60, 64, C.I. Pigment Green 7, 36, C.I. Pigment Brown 23, 25, 26, and the like. These pigments may be used alone or in combination of two or more thereof.

Pigment Yellow 138, and may be B-type quinophthalone.

Examples of commercially available products of the fluorescent coloring material include: a B-type quinophthalone pigment (C.I. Pigment Yellow 138) manufactured by Fuji Dye Kogyo Co., Ltd.; trade name “Mikawhite” ATN conc, KTS extraconc manufactured by Nippon Kayaku Co., Ltd.; and “Kayalight” B, OS, and OSN manufactured by Nippon Kayaku Co., Ltd.

The spectacle lens production method of the present disclosure includes, for example, a process of placing ink containing a coloring material on a spectacle lens (hereinafter also referred to as “process 1”) and a process of heating the spectacle lens on which the ink is placed (hereinafter also referred to as “process 2”).

The ink used in the process 1 may contain a fluorescent coloring material, a permeation auxiliary, a high boiling point solvent, and water.

A content rate of the fluorescent coloring material in the ink may be 1 to 15 mass %, may be 2 to 10 mass %, may be 3 to 8 mass %.

The permeation auxiliary may be a nitrogen-containing cyclic compound, and may be N-methyl-2-pyrrolidone from the viewpoint of enhancing permeability and improving mark distinguishability.

A content rate of the permeation auxiliary may be from 0.1 to 10 mass %, may be 0.5 to 10 mass %, and may be 1.0 to 5.0 mass % from the viewpoint of enhancing the permeability of a color material in ink.

Examples of the high boiling point solvent include oxyethylene such as triethylene glycol, tetraethylene glycol, tripropylene glycol, or an oxypropylene addition polymer; triol such as glycerin; thiodiglycol; lower alkyl glycol ethers such as triethylene glycol mono-ethyl ether and triethylene glycol mono-butyl ether; lower dialkyl glycol ethers such as triethylene glycol diethyl ether, tetraethylene glycol dimethyl ether, and tetraethylene glycol diethyl ether. These high boiling point solvents may be used alone or in combination of two or more.

Among these examples, glycerin may be better as the high boiling point solvent.

A content rate of the high boiling point solvent may be 30 to 80 mass %, may be 35 to 70 mass %, and may be 40 to 60 mass % in the ink.

Examples of the water include tap water, pure water, ion-exchanged water, and the like.

A content rate of the water in the ink may be 30 to 80 mass %, may be 35 to 70 mass %, and may be 40 to 60 mass %.

From the viewpoint of placing ink by an inkjet recording method, viscosity of the ink may be 1 mPa·s or more, may be 5 mPa·s or more, and may be 10 mPa·s or more, and; may be 40 mPa·s or less, may be 35 mPa·s or less, and may be 30 mPa·s or less.

The viscosity of the ink is measured by using an E type viscometer (e.g., “RE-80L viscometer” manufactured by Toki Sangyo Co., Ltd., and the like) under the condition of a temperature condition of 25° C. in accordance with JIS Z 8803.

A pH of the ink may be 3.0 or more, may be 3.5 or more, and may be 4.0 or more, and; may be 12 or less, may be 11 or less, and may be 10 or less.

The pH of the ink can be measured by using a pH meter (e.g., trade name “D-51” manufactured by HORIBA or the like) under the condition of a temperature condition of 25° C.

In the process 1, an ink placement method may be selected in accordance with a mark formed on a spectacle lens and is not particularly limited, and examples thereof include an inkjet recording method, a stamp, and the like.

Examples of the inkjet recording method include: (i) a continuous system in which printing on an article is performed by continuously jetting ink droplets from a nozzle and controlling jetting directions of the droplets by electric charge; (ii) an on-demand system in which an ink droplet is selectively jetted from a nozzle by applying pressure only at the time of printing; and the like.

Among these methods, the on-demand system may be better. Examples of the on-demand system include a piezoelectric system and a thermal system.

These inkjet recording methods may be performed by a known method.

In the process 2, a spectacle lens on which ink is placed is heated in order to permeate the ink.

A heating temperature in the process 2 may be 50 to 120° C., may be 60 to 110° C., and may be 70 to 100° C. from the viewpoint of permeating the ink.

After the above-described heating, operation to remove the ink remaining on the spectacle lens may be performed.

Note that a primer layer, a hard coating film, and an anti-reflection film may be formed by a known method.

FIG. 16 is a cross-sectional view to describe a structure of a spectacle lens 500 of the second embodiment. The spectacle lens 500 of the present embodiment includes a substrate 510, a primer layer 520, a hard coating film 530, an anti-reflection film 540, and a stealth mark 501 formed in the hard coating film 530 in a manner impregnated with a color material.

FIG. 17 is a schematic diagram illustrating a structure of a spectacle lens according to the third embodiment. The spectacle lens of the third embodiment includes, as a stealth mark 501, a design reference point 501c and a frame pattern 501d.

Since the design reference point 501c cannot be visually recognized under the visible light, there is no problem in use as an ordinary spectacle lens even in a case where the design reference point is printed relatively large. On the other hand, since the design reference point can be clearly visually recognized when irradiated with light having a predetermined wavelength, operators in a factory and a store can easily confirm the design reference point, and no skilled technique is required.

FIG. 18 is a schematic diagram illustrating a structure of a spectacle lens according to the fourth embodiment.

The spectacle lens of the fourth embodiment includes, as a stealth mark 501, a two-dimensional code 501a, an alphanumeric character 501b, and a design reference point 501c. The two-dimensional code and the alphanumeric character are formed of an impregnated region provided on a concave surface. The design reference point is formed of an impregnated region provided on a convex surface.

A substrate of a spectacle lens usually contains an ultraviolet absorber. Therefore, the stealth mark provided on the concave surface does not become visible even in a case of being irradiated with ultraviolet light from the convex surface side. In other words, even in a case where the stealth mark is located under an ultraviolet light environment like black light, the stealth mark is not observed from the convex surface side.

On the other hand, since the design reference point is provided on the convex surface, in a case of using the design reference point for alignment during production, there is no influence of refraction of the substrate and a position can be accurately identified.

FIG. 19 is a schematic diagram illustrating a use mode of the spectacle lens according to the present disclosure.

The stealth mark 501 may not be necessarily formed near the boxing center but inside the frame pattern.

In the spectacle lens of the present disclosure, since the stealth mark is formed near the boxing center or inside the frame pattern, the mark remains even after lens shaping work, and identification information of the spectacle lens can be read even after the spectacle lens is delivered to an end user.

Therefore, there is no problem in usual use as a spectacle lens, and history information on a spectacle from production to distribution of the spectacle lens can be managed by a stealth mark. As a result, a spectacle store can utilize the spectacle lens management system of the present disclosure for customer management, customer support, and after-sales service, more specifically, can utilize the system as: a chart-less system by managing customer clinical records with electronic data; a sales promotion tool to manage spectacle lens manufacturer's product warranty, store's product warranty, issuance timing of a direct mail; assistance for reproduction of a spectacle lens, and the like.

As illustrated in FIG. 2, the second embodiment of the present disclosure is the spectacle lens management system 1 including:

the terminal device 100a installed in a factory, and having the stealth mark input unit 101 that reads and inputs identification information from a stealth mark that is invisible under visible light and visible under a predetermined wavelength;

the terminal device 100b installed at a sales office of a spectacle lens manufacturer, and having the stealth mark input unit 101 that reads and inputs identification information from a stealth mark that is invisible in the visible light region;

the terminal device 100c installed in a spectacle store, and having the stealth mark input unit 101 that reads and inputs identification information from a stealth mark that is invisible under the visible light and visible under the predetermined wavelength; and

the management device 200 including: the storage unit 201 that stores management information I on a spectacle lens; and the data processing unit 202 that receives identification information from the stealth mark input unit 101 and selects, from the storage unit 201, management information i corresponding to the stealth mark,

in which the stealth mark input unit 101 includes the stealth mark reading unit 102 that reads a stealth mark which is invisible under the visible light and visible under light of the predetermined wavelength and includes an impregnated region formed from a fluorescent coloring material and formed on the spectacle lens.

Since surface treatment information, layout information, and the like in a producing process are displayed as the management information, information corresponding to an individual spectacle lens can be displayed, and therefore, a paper instruction attached to a spectacle lens can be eliminated in a factory.

A store generally creates a clinical record for each customer in accordance with prescription information at the time of producing a spectacle, but a large storage space is required in the store. A paper clinical record created by the store can be substituted by managing customer clinical record information with the spectacle lens management system of the present embodiment.

In a case where there is a spectacle reproduction order from an end user, a store staff can easily place an order for reproduction without obtaining necessary information for reproduction, such as a prescription of the spectacle lens, by reading identification information from a stealth mark attached to a spectacle lens and transmitting the same to the management device 200 by using the spectacle lens management system of the present embodiment.

Lastly, the third to fifth embodiments of the present disclosure will be summarized using the drawings and the like.

As illustrated in FIG. 12, the spectacle lens production system 2 according to the third embodiment of the present disclosure includes the terminal device 110 and a processing device 300,

the terminal device 110 includes the stealth mark input unit 111 that reads and inputs a stealth mark which is attached to a spectacle lens before lens shaping work and invisible under visible light and visible under a predetermined wavelength,

the stealth mark input unit includes the stealth mark reading unit 112 that reads a stealth mark which is invisible under visible light and visible under light of the predetermined wavelength and includes an impregnated region formed from a fluorescent coloring material and formed on the spectacle lens, and

the processing device 300 includes the processing unit 301 that processes a spectacle lens before the lens shaping work on the basis of the stealth mark input to the stealth mark input unit 110.

As the stealth mark used in the present embodiment, a design reference point, a frame pattern, and the like may be better. Positioning can be performed by reading a design reference point by irradiating, with the predetermined wavelength, a spectacle lens installed in the processing device.

As illustrated in FIG. 13, the spectacle lens production system 2 according to the fourth embodiment further includes the management device 200 in addition to the spectacle lens production system 2 according to the third embodiment.

The processing device 300 performs processing on the basis of management information transmitted from the management device 200. Since information corresponding to an individual spectacle lens can be displayed by displaying a recipe in a producing process as the management information, a paper instruction attached to a spectacle lens can be eliminated in a factory, and furthermore, a mix-up handling for a spectacle lens can be prevented.

As illustrated in FIG. 14, the spectacle lens production system 2 according to the fifth embodiment further includes the inspection device 400 in addition to the spectacle lens production system according to the fourth embodiment.

The inspection device 400 includes: the inspection unit 401 that inspects a spectacle lens after processing; and the defect determination unit 402 that determines a defect on a spectacle lens by comparing management information selected by the data processing unit with inspection information obtained from the inspection unit.

The processing device 300 compares the management information transmitted from the management device 200 with the inspection information obtained from the inspection unit, and determines a defect of the spectacle lens. Since a defect of a spectacle lens can be determined from information corresponding to an individual spectacle lens, and a mix-up handling for a spectacle lens can be further prevented.

Lastly, the first to fourth embodiments of the spectacle lens of the present disclosure are summarized using the drawings and the like.

As illustrated in FIG. 15, the spectacle lens 500 of the first embodiment has the stealth mark 501 formed near the boxing center of the spectacle lens. The stealth mark 501 is a two-dimensional code including an impregnated region impregnated with a fluorescent coloring material.

Since the stealth mark 501 is formed in an impregnated manner in the substrate 510, the stealth mark is invisible under visible light and hardly disappears even in a case where a surface of the spectacle lens is wiped or processed.

In the spectacle lens of the present embodiment, the spectacle lens becomes visible when irradiated with light having a predetermined wavelength, for example. Therefore, when the spectacle lens is used as an ordinary spectacle, the stealth mark is not visually recognized but becomes visible when irradiated with the light having the predetermined wavelength, and the two-dimensional code becomes readable.

As illustrated in FIG. 16, the spectacle lens 500 of the second embodiment includes the substrate 510, primer layer 520, hard coating film 530, anti-reflection film 540, and stealth mark 501 that is formed in the hard coating film 530 in a manner impregnated with a color material.

As illustrated in FIG. 17, the spectacle lens of the third embodiment includes, as the stealth mark 501, the design reference point 501c and the frame pattern 501d.

Since the design reference point 501c cannot be visually recognized under the visible light, there is no problem in use as an ordinary spectacle lens even in a case where the design reference point is printed relatively large. On the other hand, since the design reference point can be clearly visually recognized when irradiated with light having a predetermined wavelength, operators in a factory and a store can easily confirm the design reference point, and no skilled technique is required.

As illustrated in FIG. 18, the spectacle lens of the fourth embodiment includes, as the stealth mark 501, the two-dimensional code 501a, alphanumeric character 501b, and design reference point 501c. The two-dimensional code and the alphanumeric character are formed of an impregnated region provided on a concave surface.

A substrate of a spectacle lens usually contains an ultraviolet absorber. Therefore, the stealth mark provided on the concave surface does not become visible even in a case of being irradiated with ultraviolet light from the convex surface side. In other words, even in a case where the stealth mark is located under the ultraviolet light environment like black light, the stealth mark is not observed from the convex surface side. On the other hand, since the design reference point is provided on the convex surface, in a case of using the design reference point for alignment during production, there is no influence of refraction of the substrate and a position can be accurately identified.
